[arm-allstar] Link Activity Timer Not Always Working

[Larry Aycock]

Hi David,

No, this problem has been occurring for a while now but has been happening more frequently within the last week or so.  Before, it would only do it on my dad's node very rarely.  Now, my friend's repeater is also doing it, and the frequency of the two disconnecting and not reconnecting has significantly increased.  I moved the hub node to a cloud server this morning for various reasons, one of which was to eliminate the possibility that it might be something wrong with my repeater node.  However, after setting up the cloud hub, one of the other nodes has already disconnected and didn't reconnect, indicating the problem still exists and wasn't an issue with my repeater node.

I had to use ASL for the cloud node since I don't think I can install HamVoip on a virtual server.  However, the other three nodes (my repeater, friend's repeater, and my dad's node) are all running the latest version of HamVOIP.  I'm not sure what dual-registration is, so I can't answer that question.

Larry,

Did this problem start after changing to using a VPS-based hub node?

Are you using HamVoIP dual-registration?

I have my repeater node, a friend's repeater node, and my dad's simplex node connecting to my hub node.  On my repeater, my friend's repeater, and my dad's node, we use the link activity timer to disconnect all nodes and reconnect back to my hub node.  As I mentioned, this has been working for the most part.  
However, on my friend's repeater and my dad's node, it will occasionally disconnect from the hub, and won't reconnect.  Hours will pass and it will not reconnect back to the hub.  Eventually, one of us will notice the link is down, and send the command to run the script, and it reconnects back to the hub.  Nothing has changed on either of the nodes, and it seems like this problem is occurring much more frequently within the past week.

I moved the hub node to a cloud server for several reasons, but was also trying to troubleshoot this problem.  Unfortunately, even once I moved the hub to the cloud, I found the problem with the two nodes remaining disconnected is still happening.  I am baffled by this problem because it doesn't always happen.  I have not been able to consistently recreate the problem, so I have not been able to identify the cause.

Remember that I am not having this problem with my repeater, but the same lines are used in my dad's and my friend's rpt.conf files.
